Summary

This study explores whether the frontal QRS-T angle, measured from a standard 12-lead ECG, can serve as a marker for collateral circulation in patients with chronic total occlusion (CTO) — a condition where a coronary artery is completely blocked. Researchers will compare ECG readings with coronary angiography results, which directly visualize these collateral vessels, in 100 patients. The goal is to see if a non-invasive ECG measurement could help assess the heart's natural bypass network.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: 12-lead electrocardiogram (ECG) and coronary angiography
What this could lead to: If the frontal QRS-T angle reliably indicates collateral circulation, doctors might use a simple ECG to gauge heart health in CTO patients, potentially reducing the need for invasive angiography.
What could go wrong: This is an observational study with a modest sample size, so the findings may not apply to all patients. The ECG marker might not be accurate enough to replace angiography in clinical practice.
